e ,Application sied Aprnza ToczZZ whomiz may concern: f f Be it known that'I, WILLIAM E. COLLINS, a citizen of the United States, residing at Cambridge, in the county of 'lVashington and State of New York, khave invented cer tain new and useful Improvementsin BOX- Fasteners, of which the following is a speciiication. My y inventioni relates to locking devices for securing the lids of shipping cinteso'ru other receptacles which` are used in trans-- porting goods and which are returned when empty for reiilling.

Shipping crates or boxes are subjected to great strains and shocks during transportation and it is necessary to provide a very rigid and strong fastening device and yet one which may be readily unfastened. Furthermore, it is desirable that the locking means should not project from the sides of the crate as it will then be more liable to injury or to catch in other goods.

The object of my invention is to provide4 a fastening device which is substantially flush with the sides of the crate, of great strength, forming a secure lock and which may be fastened or unfastened.

In the accompanying drawings which form a part of this specification, Figure 1 is a perspective view of a locking device em bodying my invention with a shipping crate or boX shown in outline in dotted lines to illustrate the manner of applying the lock; Fig. 2, is a vertical section of the same; Fig. 3 is a horizontal section on the line 3 3 of Fig. 2; Fig. 4 is a front elevation of the lock casing; and Fig. 5 is an enlarged detail of a portion of the end wall of the crate or box covered by the lock casing and showing the manner of cutting a groove'or recess to receive the securing wire.

The lock casing is channel shaped having a top member 2 and depending side members 3 and 4 which fit over the upper edge of the box side and are secured by screws 6. 'Ihe casing may be made of any suitable metal and is preferably stamped from sheet steel. The sides hug the walls of the boX side and oifer no obstruction, being substantially flush therewith. The stem S of the coperating members of the fastener which projects from the lid is adapted to pass through a hole 10, in the top Vplate of the casing, and extend into the recessf12, cut in the top edge of the boX side.

lid of the craterigidly andsecurely in closed position. It will be observed that any tendency of the lid to move upwardly is resisted by the wire 14 which bears againstthe underside of the topk plate of the casing. To permitthe curved .securingor lock-ing wire 14to be readily passed or threaded through the hole I15in the stem, I provide holes 1S, vin thefront or face plate "3 of` the casing, the wire being preferably vcurved upon an arc which passes through the holes18 and the aperture 15 ofthe stem. To facilitate the threading operation yI provide either a single sight hole 20,k or two holes 20"?, 20h, separated by an integral rib, the latter being the stronger construction. After the wire 14 has been threaded through the stem,

a transverse holejl in the stem 8, locks the fiov the ends may be bent inwardly, as shown in i to this end I have shown the plate provided with a central boss 22,*to which the stem is riveted and through which it passes, surrounded by a metal ller or washer 24. This n construction not only provides a strong anchorage for the stem 8, but the boss 22 which fits into a recess in the lid takes up the thrusts and shocks to which the crate is sub- 'jected and relieves the strain which would otherwise be placed upon the screws and which would tend to wrench the plate from the lid.

The important advantage of my invention will be apparent from the above description. n v

It affords a lock which is substantially flush with the sides .of the boX or crate and is exceedingly rigid and strong. The side thrusts to which the crate is subjected during the usual rough handling of transpor` tation are transmitted to the sides andA lid of the box without placing any strain upon v the screws by which the stem-plate and lock casing are fastened. Any direct pull tend# ing to lift the lid is transmitted through the stem and securing plate directly. to the underside of the top plate ofthe casing. The direct pull or thrust transmitted through the .Titi

stem to the wire 14 is exerted close to the stem Where it cannot bend the Wire but must act as a shearing strain, so that 4there is no tendency to loosen under repeated shocks. y A

Thile I have described in detail the pai'- ticular construction illust-rated in the raoco'mpanying drawings for the purpose'o'f disclosing `an embodiment of .my invention', it is evident that various changes and modifieations may be made therein Within the scope of my claim and Without departing from the Spirit of my invention.

I claim:- 1 p A y box fastener, comprising a channel shaped casing adapted to lit over the edge of a box side and having a hole in its top member Yand two holes in its outer side member spaced upon either side of said rsts named hole, a plate adapted to be secured 20 to the boxl lid and having a vdepending stem adapted to pass through said hole in the top 'member when the lid is Closed, said stem being provided With a transverse hole, and a locking member adapted to be threaded 2 through said holes in said outer side member and said stem.

In testimony whereof I affix my signature in presence of tivo Witnesses.
